The Permissibility of Expressing Satisfaction with the Companions and the Successors

Question:
The questioner (As'ad A. A.) from the Eastern Region also says in this question: Your Eminence! As is known, it is obligatory for us when the Companions (may Allah be pleased with them) are mentioned, and during our recitation, to say: But if a Successor or one of the righteous Salaf is mentioned and we also say: Is there any harm in that?

Answer:
There is no harm in this if he says: regarding the believers, even if they are from the Successors or the followers of the Successors. However, the custom among the scholars has become established to express satisfaction with the Companions and to invoke mercy upon those who came after them. The matter is broad in this regard, and praise be to Allah. So, when a Companion is mentioned, he says: And when a Successor or other scholar or righteous Muslim is mentioned, he says: (may Allah have mercy on him). And if he says: there is no harm, and praise be to Allah. It is all good.
